3.2 Powering up the PIR sensor

•  Remove  the  screw  from  the  bottom 

part  of  the  top  plastic  cover  with  the 

screw driver (as shown in diagram) and 

install  the  1  x  CR123  lithium  battery 

(Fig. 2).

• Low battery indication: The battery status can be checked either on the panel or controlled APP 

under the “EVENT History”. When the battery is in low battery status, the "battery ICON" will be shown 

under the sensor triggered record. Change the battery to make sure the sensors can work properly.

 

3.3 Installing the PIR sensor

• Ensure the mounting surface is clean.

• Peel off the surface of the adhesive pad of the mounting bracket and then attach it onto the wall.

• Or drill the holes and insert wall plugs and then attach the bracket provided to the mounting surface 

with the screws provided.

• Finally attach the Motion Sensor to the mounting bracket.

3.4 Sensor sensitivity

IIMPORTANT! The PIR sensor is designed with a built-in sleep timer to save battery power. The PIR 

sensor will sleep for 3 minutes after every trigger. Any movement detected in sleep mode will not be 

reported, please bear this in mind during system set up.

The sensitivity of the PIR Sensor is adjustable and can be changed by setting the connector, found in 

the battery compartment with either “H”- High”, “M”- Middle or “L”- Low position. (Detection range: 

“H”< 13m, “M” < 8m, “L” < 5m, depends on the environment status). When the sensitivity is set to 

“Low”, more movement is required to trigger the sensor. 

It is recommended to set the sensitivity to “Low” and perform a “Walk Test” (Described in part 3.5). If 

the walk test result is satisfactory, the sensitivity does not require further adjustment. If the walk test 

result shows the sensitivity is too low, then the sensitivity can be set to “Middle” or “High” as required. 

3.5 Walk test

After mounting the sensor at the desired location, it is important to 

perform a walk test in order to determine if the sensor is detecting 

the correct area. The distance at which the sensor can detect 

motion can be adjusted by altering the angle of the sensor. To 

reduce the detection range, simply move the sensor downward 

and move the sensor upward to maximize the range.

Note: Enter into ALERT mode before you perform the walk test, so 

that the alarm is not triggered.

Testing mode 

– After powering up, the Motion Sensor will enter into the testing mode for 10 minutes. 

The Motion Sensor will sleep for 10 seconds of each trigger only instead of the regular duration 3 

minutes. It is more convenient for the user to perform walk test.

You should walk in the area that you would like the sensor to monitor. If movement is detected the red 

light inside the unit will appear. If the red light does not appear, adjust the mounting angle accordingly. 

Perform the walk test again. Repeat this procedure until motion is detected.
